Enum ParseError 

#[non_exhaustive]
pub enum ParseError {
    Empty,
    NoNumber(usize),
    NoUnit(usize),
    UnitOutOfSequence(usize),
    InconstantUnitWithoutDate,
    DateOutOfRange,
    NumberOutOfRange,
    InconstantUnitWithFraction,
}

An error parsing the text, with some attempt made to be specific.

Note that the DateOutOfRange variant only catches cases where the date used for year and month math goes out of range for the type. It does not catch other overflows.

This is marked non-exhaustive to allow narrowing down error types in the future without that breaking the API so much.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

NoNumber(usize)

NoUnit(usize)

UnitOutOfSequence(usize)

InconstantUnitWithoutDate

DateOutOfRange

NumberOutOfRange

InconstantUnitWithFraction

Trait Implementations

impl Debug for ParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ParseError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<TryFromIntError> for ParseError

fn from(_value: TryFromIntError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
